BARB-WIRE MACHINE.

SPECIFKCATION forming part of Letters Patent N0. 740,220, dated September 29, 1903.

Application filed June 26, 1903. Serial No. 163,192. (No model.)

To all whmn it may concern.-

Be it known thatl, New J. BILLSTROM, a citizen of the United States, residing at Rock- I ford, in the county of Winnebago and State means for moving it.

of Illinois,have invented certain new and useful Improvements in Barb -Wire Machines, of which the following is a specification.

The object of this invention is to construct a barb-wire machine in which some of the op erative parts are mounted on a table having a swinging connection with a stationary support and means for imparting movement to the table.

In the accompanying drawings, Figure 1 is a plan view of myimproved barb-wire machine. Fig. 2 is a side elevation. Fig. 3 is an elevation of the table and mechanism for moving the table, the table being at one end of its movement. Fig. 4: is a similar elevation in which the table has been moved. Fig. 5 is a vertical section of the twister-head on dotted line a, Fig. 1. Fig. 6 is a section showing the mechanism for imparting movement to the twister-head. Fig. 7 is a plan view of the means for moving the feeding-rolls for the wire from which'the barbs are cut. Fig. 8 is an end elevation of the table and the Fig. 9 is a section of a portion of the main frame,showing the adj ust ment for taking up the wear of the knife.

In barb-wire machines, so far as known to me, the table supporting the operative parts has a slidable connection with the main frame, and owing to the rapid wear of the parts the table has soon to be replaced at great cost; and it is the object of my invention to overcome this objection by imparting a swinging movement to the table, so that the table will be free of any wearing connection with the main frame.

The main frame 1 is supported by legs 2. This main frame has a central opening 3. A main drivingshaft 4 is supported in boxes 5 and supports a pulley 6, spur-toothedwheel 7, and two eccentrics S and 9.

A secondaryshaft 10 is supported in bearings 11 and supports a toothed wheel 12, meshing with the spur-toothed wheel 7, and two feed-rollers 13 and 17 for the line-wires.

A table 18,sn pporting the operative parts of the machine, is supported in a swinging manner by a frame 19, having a connection with the under side of the table. A rock-shaft 20 is supported in stationary bearings 21 and has two vertical end arms 22 and a central horizontal arm 23. The lower ends of the frame 19 have a pivotal connection with the upper ends of the vertical-arms 22 of the rock-shaft. From the under face of the table depend two ears 24, to which is pivoted one arm of a hell-crank lever 25, and the other arm of this bell-crank lever has a connection with the horizontal arm 23, extending from the rock-shaft, by a link 26. The center portion of the bell-crank lever has a pivotal connection with the main frame of the machine by the link 27. A connection is formed between the eccentric 9 and the table 18 by the rod 28. During the rotation of the eccentric 9 a reciprocating movement will be imparted to the table, and through the various pivotal connections the table will be held in a horizontal position and will be slightly lowered and elevated during its movement's, but not enough to interfere with the proper working of the operative parts carried thereby. The table 18 supports the twister-head, knife, and feed-rollers for the wire from which the barbs are out. The twister-head 29 is supported in a bearing 30, connectedto the table in a manner to rotate therein,andhasa toothed pinion 31 connected to one end and a twister-pin 32 supported by its other end. A toothed wheel 33 is located beneath the pinion 31- and meshes therewith and has a beveled toothed pinion 3t revolving with it. From the bracket 30extends an arm 35, supporting a shaft 36, to which is connected a beveled toothed wheel 37', which meshes with'the beveled toothed pinion 34:. A toothed ratchet-wheel 38 has a connection with the shaft 36. An arm 39 is loosely supported by the shaft 36, and to its free end is pivotally connected a rod 40, having a connection with the eccentric S by the screwthreaded rod 41. A dog 42 has a pivotal connection with the arm 39 and engages the teeth of the ratchet-wheel 38. As the eccentric 8 revolves the arm 39 will be oscillated on the shaft and the dog 42 will engage the ratchetwheel, thereby im parting an intermittent rotary movement to the beveled toothed wheel 37, and through the chain of gearing an intermittent rotary movement is imparted to the twister-head 29. g

The stationary knife 43 and the movable knife 44 are of an old construction with the exception of the block 45, having a slidable connection with the main frame, and an adjusting-screw 46 for moving the block. This block is placed within the path of the lower arm 47 of the knife and against which it strikes in the movement of the table, thereby tipping the knife toward the stationary knife. At the point of contact between the lower arm of the knife and the block great wear takes place, and by means of the adjustable block this can be taken up, so that the knife will do its'work properly.

The feed-wheels 48 and 49 for the wire from which the barbs are cut are supported in a bearing 50, connected to the table, and have a gear connection.

A ratchet-wheel 51 has a connection with the stud 52, connected with the wheel 48, and an arm 53 moves around this stud and supports a dog 54, capable of engaging the ratchet-wheel.

A spring-actuated dog 55 has a pivotal connection with the bracket 50 and engages the ratchet-wheel 51. To the main frame of the machine is pivoted a bar 56, one end having a connection with the arm 53 of the link '57, and the other end, being slotted, receives a stud 58, extending from the table. Asthe table moves back and forth the bar 56 Will be rocked onvits pivot, which will oscillate the arm 53, causing the dog 54 to move the ratchetwheel 51, thereby imparting movement to the wheels 48 and 49, and force the wire from which the barbs are made past the twister-head suificiently to make the required number of wraps. The dog 55 holds the wheels 48 and 49 from further advancing movement. From the arm 53 extends a projection 59, which engages a stud 60 on the dog 55, so that the dog 55 may be moved free rotation of the main driving-shaft rotates the wheels feeding the line-wires and also moves the table away from the main shaft, which will move the movable portion of the knife and rotate the twister-head. The return movement of the table will rotate the wheels feeding the Wires from which the barbs are cut, all of the movements having before been described. The spring 61, secured to the bearing 30, embraces the end of the twisterhead and allows the head to move in its lengthwise direction as the barb is being twisted around the lengthwise wires.

I claim as my invention-- 1. In a barb-wire machine, the combination of a main frame, a table, means for imparting a swinging movement to the table, a twisterhead, knife and wheels for feeding the wire from which the barbs are cut supported by the table.

2. In a barb-wire machine, the combination of a main frame, a table, means supporting the table in order that it may have a parallel swinging movement, and means for moving the table.

3. In a barb-wire machine, the combination of a main frame, a table capable of a swinging movement and an eccentric for imparting movement to the table.

4. In a barb-wire machine, the combination of a main frame, a swinging table, a twisterhead supported by the table, an eccentric, a bevel-gear and ratchet connection between the eccentric'and twister-head.-

5. In a barb-wire machine, the combination of a main frame, a table, a twister-head supported by the table capable of lengthwise movement, a strap-spring having one end rigidly connected and its other end exerting its influence on the twister-head.

6. In a barb-wire machine, the combination of a main frame, a table, wheels supported by the table for feeding the wire from which the barbs are made, means for imparting movement to the wheels consisting of a ratchetwheel, an oscillatory arm supportinga dog and a retaining-dog, the arm having a projection engaging the retaining-dog.
